My invention relates to hydrocarbon burners, and more particularly to.certain improvements concerning my Patent.' No.

1,238,003, granted August 21st, 1917.

The improvements consist primarily in devisinga single burner incoritra-distinction to -one'of the duplex or multiple type; devising-atype of burner head with 'a maximum surface upon which the atmospheric*air may exert a cooling effect; providing for a more completeattenuation of the gas which goes to make up the combustible'mixture;`mounting the .overlying retort in a novel fashion so that it. .may bequickly dismantled; and providing an intake which will precludeback-firing.

With these and other objectsin view, the

invention coniprises'the arrangement-and construction of parts showninthe accompanying drawings, hereinafter' described,

and embraced within 'the scope of the appended claims.

In said drawings:

Wardly from the wall ofthe mixing cham sion of air to all Aof its parts.

ln practical operation the nipple 17 is connected with a suitable sourceof kerosene or other similar hydrocarbon, and the kerosene gravitate'sinto the retort'lS. A small `qlmntity of alcohol is then placed in thetWo troughs 30, which are formed in the top of Wall 8, below and just toone side of the retort, andA this alcohol is 'ignited andthe heat,arising therefromserves to preliminarily vaporize the kerosene in theretort, so that it Will be atomized through the opening 22 of nozzle 21in the form of an exceedingly tine spray. At the same time, it Will beunderstood that the vaporized kerosene mixes with air in the mixingchamber 20, the air and vapor forming a combustible mixture Vwhichpasses on through the intake 27 and then into the burner head proper,Where it is ignited andthe flame issues through the different sets ofkerfs. The Haines from the upper set ofi' kerfs 10 then take up the Workof the alcohol and automatically superheat the kerosene in the retort 18to the desired degree. Simultaneously the liames are emit.- ted from thevertical kerfs in the'side of the burner, and besides giving the heatrequired for any special purposethe flames issuing from the vkerfs onthe opposite'sides of the housing 12 manifestly heat the housing so thatthe air entering therethrough into the mixing chamberavill be initiallyheated by the time it arrives at a point directly in front of theatomizing nozzle 21. In this manner both the hydrocarbon and the air areheated and their admixture greatly facilitated. The novel form of intakenot only prevents backfiring or puffing, but also servesv to attenuatethe or admixture so that complete combustion will ensue W hat is claimedis:
